Research Abstract

We have achieved resonance between triplet excited state in organic layers and Wannier exciton state in inorganic layers in self-organized organic-inorganic perovskite-type compounds. We have observed an enhancement in a phosphorescence peak in near resonance with the Wannier exciton. The results indicate that the resonance effects are applicable to development of novel luminescent materials.
